NGFW / Network Security · head-to-head
Cisco vs Fortinet
Next-gen firewalls and hybrid-mesh network security. Counts are scoped to this segment and the selected published-date window. Fortinet carries 3.5× the disclosed CVE volume of Cisco. Volume reflects disclosure practice and install base as much as code quality — read it with the severity mix. Sourced from the NIST NVD; lower counts indicate a smaller disclosed vulnerability surface — not necessarily lower risk.
